I have a 12 inch Cerwin Vega sub I don't need. I might have a possible sale on it but highly doubtful. What state are you in? Why a 10"? Looking for something small? Let me know if you are interested.
I've got a DCM SW10 along with a 12' Monster sub cable that I am selling. I'm asking $120 + shipping. It has one small ding in the bottom front edge but it could easily be covered up.
I'm selling a 12" Sony SA-WM40. It's been sitting in the original box for like 2 months. I told myself I was going to sell it but it just didn't seem to happen... I'm only asking $135 shipped. I'll tell you it has a fairly small footprint and is definitly worth looking at.
